Computerized Assessments & Learning JavaScript Developer interview questions

In person interview with the team. A few questions on background, some light technical questions. They asked if I looked at the code challenge. Apparently they never sent it to me. After the interview I received the code challenge. It was vague and contradictory. I worked on it listing assumptions I had to make so that it would work. When I went in for the second interview. I asked what a successful answer would look like and they admitted they didn't actually know. As I was walking through the code, I had to explain some basic features of the language (.call()). A week later, they asked for references and they contacted them. A week after that, they asked that I do the exact same code challenge with a few modifications. I sent it to them and then. . . nothing. No phone call. No email. Guess they weren't interested, but it was the rudest experience I've ever had in a professional setting.
